A contingency sale in real estate lets you make an offer on a new home that depends on selling your current one first. The purchase contract stays conditional until your existing home sells by a deadline written into the agreement. Miss the deadline and, if the clause is drafted properly, the deal ends and your earnest money comes back. How much protection you actually get depends on which type of contingency you use, how tight the deadlines are, and whether the seller attaches a kick-out clause.
The Two Types of Contingency
Not every contingency carries the same risk, and sellers read them differently.
A sale and settlement contingency is the version used when your current home isn’t under contract yet. The deal is conditional on finding a buyer and closing that sale, usually within 30 to 60 days. If no buyer appears, the contract terminates and your deposit is returned. Sellers are wary of this version because it hinges on an event that hasn’t started yet.
A settlement contingency applies when you already have an accepted offer on your current home and only need to get through closing. The hardest work is done: a buyer is lined up, price is agreed, inspections are behind you. Sellers prefer this one because the risk of collapse is much lower, though it isn’t zero. Your buyer could still lose financing or back out during final due diligence.
What the Contract Has to Spell Out
A contingency contract carries more moving parts than a standard purchase agreement, and the details are what determine whether you actually walk away clean if things go sideways.
Expect to hand over the listing price of your current home and evidence that it’s actively on the market, such as the listing agreement or MLS link. The seller wants to judge whether your property is priced to move or sitting at a number that suggests months of waiting.
Two deadlines drive everything. The first is the date by which you must have a signed contract on your existing home. The second is the final closing deadline, sometimes called the drop-dead date, after which the whole agreement expires. Both are commonly set 30 to 60 days out from the day the purchase agreement is signed, though you can negotiate any timeframe.
The earnest money language matters as much as the dates. Deposits usually run one to three percent of the purchase price, and vague wording is where disputes start. The contract should say plainly that if your home doesn’t sell by the deadline, the deposit is returned in full without requiring the seller’s consent.
The Kick-Out Clause
Sellers who accept a contingent offer almost always insist on a kick-out clause, and it’s the part of the deal that most often surprises buyers. The clause lets the seller keep showing the property and taking other offers. If a stronger, non-contingent offer arrives, the seller notifies you and starts a countdown.
You then have a narrow window, usually 24 to 72 hours depending on the contract, to make a choice. Either waive the home sale contingency and commit to buying without relying on your sale proceeds, or walk away with your earnest money. There is no middle ground. If you can’t prove you have the funds to close on your own, you lose the house to the backup offer.
Proving funds means liquid money you can wire on closing day: a bank statement, certified financial statement, or letter from a financial institution showing enough to cover the down payment, closing costs, and escrow. Retirement accounts, stock portfolios, and life insurance generally don’t count because they aren’t immediately accessible.
That 24-to-72-hour window is not enough time to arrange financing from scratch. If you want a realistic shot at surviving a kick-out, line up a backup funding source before you submit the offer, whether that’s a bridge loan approval, a HELOC in place, or savings you haven’t committed elsewhere.
How the Closings Fit Together
When a contingency sale works, it ends with two closings happening back to back, sometimes on the same day. Real estate professionals call it a domino closing because the second transaction can’t happen until the first one falls into place.
You close on the sale of your current home first. The escrow agent or closing attorney records the deed with the county, and only after recording can the sale proceeds be released. Those funds are wired to the escrow handling your new home. You sign mortgage and title documents on the purchase side, the new deed is recorded, and the seller receives their money.
The coordination is real work. Recording can take minutes or hours depending on the county office’s workload, and the new lender has its own funding timeline. If one closing stalls, the other stalls with it. Scheduling the sale closing as early in the day as possible creates a buffer. Some buyers build a one-to-three-day gap between closings instead of stacking them, which lowers the stress but means finding somewhere to stay for a night or two. Using the same closing attorney or escrow company for both transactions, when possible, can shave hours off the process because funds don’t have to move between different firms’ trust accounts.
What Happens If Your Home Doesn’t Sell
If your home doesn’t sell by the deadline and the contingency was properly written, the purchase agreement terminates and your earnest money is returned. That is the whole point of the clause. It’s a contractual exit ramp.
Trouble starts when deadlines slip without a clean termination. Let the contingency period expire without formally invoking it, or try to back out for reasons the contract doesn’t cover, and you can be treated as having breached the agreement. At that point the seller has options: keep the earnest money, sue for the difference between your contract price and whatever the home eventually sells for, or in some cases pursue specific performance, a court order forcing you to complete the purchase.
Specific performance shows up more in real estate than in other contract disputes because every property is legally considered unique. A seller can argue that money alone doesn’t make them whole since they can’t simply buy an identical house elsewhere. In practice, most disputes settle with the buyer forfeiting earnest money rather than going to court, but the seller’s legal exposure can extend well past the deposit if the contract doesn’t cap damages.
If you need to exit a deal by invoking a contingency, do it in writing, do it before the deadline, and follow the notice procedure the contract requires exactly.
When Sellers Reject Contingent Offers
Contingent offers carry a stigma in competitive markets. A seller with multiple offers will usually pick a clean, non-contingent bid over a contingent one, even if the contingent offer is higher. The reasoning is direct: your offer introduces variables the seller can’t control. Your home might not sell. Your buyer might lose financing. The timeline might stretch while better opportunities pass.
In a balanced or buyer-friendly market, sellers are more open to contingencies because the alternative may be no offer at all. In a seller’s market with low inventory, a contingent offer without a backup plan is often not worth submitting.
Buyers sometimes try to offset the disadvantage by offering above asking, shortening the contingency period, or putting up a larger earnest money deposit. These help at the margins. What tends to move sellers more is showing you can close even if your home hasn’t sold, usually by having alternative financing already lined up.
Alternatives if a Contingency Won’t Work
If a contingent offer isn’t competitive enough, or the seller won’t accept one, several tools let you buy before you sell.
Bridge Loans
A bridge loan is a short-term mortgage built for the gap between buying a new home and selling your old one. Residential bridge loans for primary residences exist, though fewer lenders offer them than offer investment-focused versions. Rates generally run between 6% and 12%, terms can be as short as four months, and payments are typically interest-only during the loan period. Closing costs usually add one to three percent of the loan amount. The loan is paid off when your old home sells. Bridge loans make sense when you’re confident your home will sell within a few months and you need to move fast on the purchase side.
Home Equity Line of Credit
If you have substantial equity in your current home, a HELOC lets you borrow against it for a down payment on the new property. Most lenders cap HELOCs at 85% of your home’s value minus your remaining mortgage balance. The catch is that your debt-to-income ratio now covers three obligations at once: your current mortgage, the HELOC payment, and the new mortgage. Lenders underwriting the new mortgage factor in all three, and many require a DTI at or below 50%. Applying for the HELOC well before you start house hunting gives the funds time to land and the new debt time to appear on your credit report.
401(k) Loan
Federal law lets you borrow from a workplace retirement plan up to the lesser of $50,000 or half your vested balance, with a floor of $10,000. The loan doesn’t trigger income taxes or early withdrawal penalties if you repay it according to the plan’s terms. Most 401(k) loans must be repaid within five years, though loans used to buy a principal residence can have longer repayment periods.1Office of the Law Revision Counsel. 26 U.S. Code 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts If you leave your job before the loan is repaid, the outstanding balance may be treated as a taxable distribution. This works best as a short bridge you plan to pay off from sale proceeds.
Mortgage Recasting After the Sale
If you buy the new home with a larger mortgage than you ultimately need, you can recast the loan once your old home sells. Recasting means making a lump-sum payment toward principal and having the lender recalculate your monthly payments based on the reduced balance, without changing the interest rate or loan term. Most lenders require a minimum lump sum around $10,000 and charge a processing fee near $250. This lets you make a non-contingent offer now and reduce your payments later.
Taxes on the Sale Side
Selling your current home to buy a new one can produce a capital gains tax bill, and the timing pressure of a contingency sale makes it easy to overlook. If you’ve owned and lived in your home as your primary residence for at least two of the five years before the sale, you can exclude up to $250,000 in capital gains from income as a single filer, or up to $500,000 filing jointly.2Internal Revenue Service. Topic No. 701, Sale of Your Home The ownership and use periods don’t have to be continuous. They just have to add up to 24 months inside the five-year window.3eCFR. 26 CFR 1.121-1 – Exclusion of Gain From Sale or Exchange of a Principal Residence
If you bought recently and haven’t hit the two-year mark, you may not qualify for the exclusion at all. If your gain exceeds the exclusion, the excess is taxed as a long-term capital gain. For most homeowners who have lived in a home for several years, the exclusion covers the whole gain, but in high-cost markets with significant appreciation the numbers are worth running before you commit to a sale timeline set by someone else’s contingency deadline.
